iStock/Thinkstock(NEW YORK) — At least nine people were killed when flames from a raging wildfire engulfed their vehicles in Northern California, authorities said.

Virtually the entire town of Paradise has been destroyed, according to authorities.

Four of those victims were found dead in torched vehicles and another discovered outside a vehicle in the town of Paradise, where the Camp Fire has ravaged entire neighborhoods. Autopsies will be conducted to determine the circumstances of the death and to identify the individuals, but investigators believe their vehicles were “overcome” by the flames, the Butte County Sheriff’s Office said in a statement Friday.

Three more bodies were discovered outside of residences and a fourth inside a residence, Ventura County Fire Department spokesman Steve Kaufmann said on Friday night.

Authorities have received reports of additional fatalities due to the blaze, which investigators are still working to confirm.

Rescuers had responded to 588 calls for people needing assistance, officials with the Butte County Sheriff’s Office said at a Friday evening press conference.

“The task is difficult due to the fact that the fire is still active and there are many hazards in areas where fatalities have been reported,” the sheriff’s office said.

By Friday night, the blaze had grown in size to an area of about 90,000 acres in Butte County and was just 5 percent contained, according to the California Department of Forestry and Fire Protection. Some 52,000 people have been evacuated and more than 6,700 structures in the affected area have already been destroyed.

Pulga, Concow, Magalia, Stirling City as well as the entire town of Paradise were among the areas that remained under mandatory evacuation orders Friday.

At least three of the 3,223 firefighters in the field have been treated for injuries.

The Camp Fire ignited Thursday morning in Pulga, a tiny community in Butte County nestled in the Plumas National Forest, and strong winds fanned the flames overnight, sending thousands of residents fleeing for their lives.

The blaze raced southwest overnight through the small community of Concow and then Paradise, which was largely destroyed, according to Scott McClean, public information officer of the California Department of Forestry and Fire Protection.

One of the blazes jumped the 101 Freeway on Friday morning and continued burning toward Malibu, prompting officials to order the entire city to evacuate. The other fire could spread all the way to the Pacific Ocean, authorities said.
